lleit known that l,\\'u.|.I \.u Aianan'rtutn AN, a citizen ot'the United States, residingat Yellville, in the eouutvot' Marion and State of lrkansas, have invented certain new and useful Improvements in lllowpipe-Lamps; and i do hereby declare the following to be a full, clear, and exai-t description of the invention, such as will eui'ibleothers skilled in the art to whit-h it appertaina to make and use the same.

This in vention relates to improvements in lJlUWplpQ-lillllpS lumrans of which the blowpipe is connected to the lamp in such manner thatit will provide a steady tlanie and also permit the latnp to he adjusted in order to properly direct the air from the hlowpipe.

llythe particularr-onstruet ion and arrangement of parts \Yllit'lt make up my improved blowpi pe-lamp the operator can lnaze art ieles of complicated form that could not. heretofore be reached by the ordinary lilowpipe, and at the same time there will he no change in the character of the flame.

'ith the above ends in view the invention consists in the particular(-onstrnetion ot the lamp and device carried thereby holding the lilowpipe, both lamp and lilowpipe being adapted to he adj usted with respect to eat-h other to direct the air upon the tlame.

In the aeeom muyiug drawings, forming a part of this Specification, Figure l is a perspective view of a hlowpipe-lamp eonst rut-ted in accordance with m v invention. Fig. "3 isa vertical seetional view. Fig. 3 ion trauaverse sectional view through the support to whieh the blowpipe is eonneetell.

in the drawings the numeral l deaignates llll' lamp proper, whirh eonsists ol' :1 (-irrulnr reservoir having a \l'lt'k-ltllm 2, projertiug therefrom at a tangent, the outer end of said wick-tube being threaded to l't'ltlVt: a rap 2 which is also threaded. From one side ol the reservoir projeets a lilling-tulio 1, also provided with a rap. Extending nearly around lhe periphery of this ri-rervoir is a hand theendaol' whit-hat'ei-ouuei-twi llIPiltllflllltl' l| v atrips 1, extending: arrow the sides i. the reservoir. 'iho hand and i'ounei-tlug-strips lln'leui' are so plan-rd in vonnm-tiou with lhn 5o reservoir that the ll'h'llil'll i. may have a movmnvnt hntwm-n the ends of said hand.

The lilting-tube isalso poaitiouod soars not to interfere with this movement. (in the upper part of the hand 5 is rigidlyseetlred a bracket 7, presentinga tlat horizontal portion theside edges of whirh are turned over to presentguides or ehannels tended toaupport the hiowpipe, which is eonlll ('l( i to a plate H in sliding engagement, with the guides or channels S. The plate 9 earries a clamp, which is swiveled thereon and consists: of rigid memliers ltland l1,provided with a screw-threaded aperture receiving a thumlrserew 1;, c-arryilr, a curved plate 1 adapted to he moved to and from the momhers it by the said thtnnh-serew. The pivot 14, whieh COlIltBf't'S the clamp to the sliding plate El, extends through the horizontal member of the bracket 7 and is secured to a flat; spring l5,the ends of which hca 'against. the antler side of said horizontal member of the liraelcet. By this arrangement spring-pressure is exerted not only against the sliding movementof the plate, but also against the pivotal movement of the clamp.

16 designates the hlowpipe, the outer end of which is held tirmly in the clamp to locate the nozzle 17 between the members 10 of said (-lamp. The opposite end of the bluwpipe is provided with the usual mouthpiece.

At the rear end of the lamp the band 5 is provided with a eross-piet-e l the ends of whieh are bent to emtu'are the sides of the lamp, an intermediate portion of said erossr hill being turned up to provide a projection ttl, which, with the adjoining: ends of the brat-hot, will form feet [or supporting: the lamp so that the wink-tube will he in a ver tieal position.
